Takeover On The Tallgrass Prairie: How Lespedeza Cuneata Establishes Dominance, Morgan Rae Walder
Takeover On The Tallgrass Prairie: How Lespedeza Cuneata Establishes Dominance, Morgan Rae Walder
Theses and Dissertations
Invasion ecology aims to study mechanisms by which invasive species are able to enter, establish, and spread within an ecosystem. This study analyzed Darwin’s naturalization and the biotic resistance hypotheses as the most likely explanations for invasion by an exotic legume, Lespedeza cuneata, into a tallgrass prairie. Darwin’s naturalization hypothesis posits that exotic species are less able to establish in communities that have related species, because similarity in morphology and function promotes intense competition for resources. The biotic resistance hypothesis states that competitors, herbivores, and pathogens already present in the community limit the colonization, naturalization, and persistence of invaders, therefore …
Assessing The Remanufacturability Of Office Furiniture: A Multi-Criteria Decision Making Approach, Po-Hsun Chen
Assessing The Remanufacturability Of Office Furiniture: A Multi-Criteria Decision Making Approach, Po-Hsun Chen
Theses and Dissertations
While the average life cycle of consumer goods is continuously decreasing, the amount of used product at their end-of-life (EOL) is accumulating fast at and at the same pace. Most EOL products end up in landfills, and many of which are not biodegradable. These two challenges have necessitated renewed global interest in product EOL management strategies by manufacturers, third party companies, consumers and governments. Remanufacturing is one of the EOL strategies which is highly environmental-friendly. Additionally, remanufacturing is seen as one of the highly profitable re-use business strategies. The selling price of remanufactured products is usually about 50—80% of a …
North American Butterfly Association Counts At Congaree National Park: A Case Study For Connecting Citizen Science To Management, Austin Clarridge
North American Butterfly Association Counts At Congaree National Park: A Case Study For Connecting Citizen Science To Management, Austin Clarridge
Theses and Dissertations
Citizen science is becoming an ever more popular way for scientists and resource managers to deal with needs for large temporal and spatial scale datasets. It provides a free or low cost means for collection of extensive amounts of data across time and space while acting as a public education and outreach tool, empowering communities to be involved in the management decisions being made in their back yard. Though large, well-known citizen science programs such as the Christmas Bird Counts are being used extensively for peer reviewed literature and management decisions, there are numerous smaller, local counts that have the …
A Comparison Of Framing In Two Environmental Conflicts, Alexander M. Iannone
A Comparison Of Framing In Two Environmental Conflicts, Alexander M. Iannone
Theses and Dissertations
Frames can be perspectives about people, objects, events, or settings that guide action based on past experiences and values. Conflicts are created by different stakeholders “holding conflicting frames.” Researchers in the past have used framing analysis to try and better understand environmental conflicts that tend to perpetuate for extended periods of time. A set of researchers have relied on specific framing categories and typologies as a framework for analysis. They have found that the strong presence or lack thereof certain frames can tell us a lot about conflict dynamics and shed light into the undercurrents driving the complexity of the …
